I need some help :)
My wish: I want to receive a iphone notification when 1 arduino analog input drop from 5 to 0 volt.
Then (later) when the voltage goes back to 5V i want another message.
It needs to be over Wifi (not BT).
Is there anyone that can help me with this?
Thanks in advance
It is totally doable, but we cannot give detailed tutorials here, since this is a simple Q&A site. So I will point you to a direction, that can lead you to the solution.
When building IOT devices with Arduino (and thats exactly, what you are doing) there are 2 internet services, that are commonly used for getting information from the device to other devices (like your phone):
Both have apps and can be used to push notifications, when your IOT device does a webrequest to the service. There are also libraries for Arduino available (at least for Blynk). There are many tutorials out there, so I suggest, that you search for yourself and try some of them.
For the hardware of your IOT device, I would suggest an ESP board, because they already have Wifi build in, for example the ESP32 gives you great IO capabilities.
